ASIC misfortune: Anker Uspeed USB-hub + msata SSD broke down.

[DennisD7]

Yesterday, as I was hanging out with one of my girls, I casually checked in on BTC Guild to make sure things were running smoothly at home when I realised something bad was going on. So this morning I not-so-casually raced home through the London morning commute, surprising my housemates at breakfast, and found that my Anker Uspeed 10-port USB 3 hub was on the fritz. It wasn't completely dead: there were short-lived flickers of light but, and I could run one USB erupter for a while but after a minute or so that too stopped working.

Right now I have two erupters plugged in to the existing ports, instead of my usual nine. I have ordered a new USB-hub of the same make, so I should be up and running again tomorrow. Has anybody else had any problem with this hub? Is it not suitable to run 24/7 like this?

 I'm running a bunch of these in my setup. Have not run across this problem mining 24/7 for a good while now. Sorry to hear about your trouble

Could be a power brick/power supply issue.  Once you get the second one, try swapping the power brick on the first one and see if it's still on the fritz.

Yes I'll try that. I already got an OK from Amazon for full refund though but it might give us a clue.

Thanks. Yeah I've seen it used in a lot of rigs so I thought it's a pretty solid piece of gear.

i have one of the black ones where the 4 ports nearest the power switch stopped working. Erupters plugged in there get the LED on constant and cgminer doesn't see them. I just use the ports that work and plugged the fan in one that doesn't.

I had one power supply go down out of 11 Anker 10-port hubs.  I've seen people report that it's very easy to get a replacement hub from Anker (good warranty).

i have one of the black ones where the 4-5(don't remember exact number) ports nearest the power switch stopped working. Erupters plugged in there get the LED on constant and cgminer doesn't see them. I just use the ports that work and plugged the fan in one that doesn't.

Sounds like one of the internal hubs broke down on your unit.  10-port hubs tend to be 2x4 port and 1x2 port hubs inside.

yeah, if i feel ambitious, i'll open it up and look inside. I've still got another 10 port for expansion.

I'm suspecting the power brick might have overheated, as it was lying on a wooden shelf and out of the way from the fans. Amazon will reimburse me and I get a new one today, so it'll be fine. Next setup I'll just place the brick next to the hub itself so it gets a little cooling too.

 Saw this and decided to lay a big fan on top of the hub power supplies and blowing air down onto them in my cabinet. Thanks for the tip.

I'm up and running again, with dual Ankers. I positioned the bricks so that they are getting some of the wind from the fan, I think it should be enough. The hottest part of the summer is over too.

Rig is down again, since about 50 minutes ago    I'm at work so I can't check it out, hopefully it was a short power outage and not a dual Anker hub faliure (which seems unlikely). Other theories: home internet is down, or there was a break-in and somebody stole all my stuff, or my housemates went into my room and turned off my rig.

Edit: Up and running again! It was actually the SSD on my computer that messed up, for unknown reasons. "No bootable disk" etc. I took out the msata SSD and put in again, booted up with no problem and we're back on 4 GH/s, living the dream.

  if you turn the pc off and back on too quickly.   msata some times needs to have 0 power for 1 hour to reset (crucial 256gb)

you may have bad psu for the ankers.  buy one of these for backup

 this has a bit more overhead

  also run 8 sticks and 1 fan if the room temp is high.

[DennisD7]

Right now it seems the msata SSD is the problem. I will give it a week and see if it behaves.

[DennisD7]

It's that damn msata SSD  

OK, so it's stopped working three times this week already. Last night I lost 6 hours, so I restarted it this morning and when I got into work I noticed it was off again, so that's at least 9 hours I lose today too. I'm going to connect the old ugly 2.5" HD and that should do the trick.
